Tammy, in the Origin theme both pages have the same widgets:

So, let me explain how things stand related to the Mobile version.
As it's stated in our official blog post (http://blog.oxwall.org/2013/11/oxwall-1-6-goes-live-january-8-beta-today) - we released the platform which can be used for developing the plugins in this update. Besides on the first stage we were starting with basic features and several native plugins these are Newsfeed, Photos and Notifications to show the direction for what Oxwall mobile browsing experience is going to be.
It requires to develop further instruments to make a plugin work with the mobile version. i.e. create a kind of 'addon' for a plugin.
If you check, let's say Photo plugin you will see that it has its own mobile directory which contains the functionality of the mobile plugin: its own components, controllers and classes. Hence, to make the Forum or Video plugins work with the mobile version, you will need to develop its mobile functionality.
We do realize that such plugins like Groups, Forum, Videos, etc are very important to the communities, but this was the first stage only and we are not going to stop development, but it requires time to implement all the plugins to the mobile version. Since these plugins are already scheduled for next stages and third-party developers are working on their own plugins - we are expecting that all plugins will be added sooner or later.
